The effects of digital technology on the security industry require constant vigilance by security distributors, sales staff, and installation professionals. Today and for the foreseeable future, all security professionals must have at least a basic understanding of digital technology. "Digital CCTV" addresses this new challenge.
Topics convered include compression variables such as Lossless and Lossy, which are explained by reviewing Huffman and Run Length Encoding (RLE), and by relating these forms of compression to ZIP and Stuffit, which are commonly used in personal computers. A review of JPEG, motion JPEG, MPEG and wavelet compression schemes among others, with a comparison of the merits of each, is also provided. As "Digital CCTV" traces the stream of digital video flow from the computer industry through compression, transmission, display and storage, and explains how analog video signal is converted into a digital signal, the reader will learn and understand the mysteries of digital science.
* Explains industry concepts, acronyms and buzzwords acurately and clearly
* Covers history, current complexities, and the future effects of digital science
*Provides practical information about how digital video works, how digital video is stored and transmitted, what digital systems can and cannot accomplish, and what to expect from digital video equipment in modern CCTV systems

CCTV for Security Professionals provides the information necessary to design the ideal CCTV system. The chapters are stand-alone sources of information on their subjects and are presented in logical sequence to guide the reader from basic principles to more complex for a complete system understanding.
In his straight-forward and informative text, Alan Matchett approaches the camera systems from the user's point of view, providing the security manager with the knowledge to discuss the system, its desired features, and the areas of design concern within the context of an organization's business model. This can prove to be invaluable when evaluating an existing system, the use and components of a given system, or in evaluating a system design proposed by a vendor.
Installers and service personnel will benefit from the functions and possibilities that are available with the various components and by gaining an understanding of their customers' needs. Newer technicians will learn how to set up the system properly, and can familiarize themselves with the technologies that go into a CCTV system.
Security equipment sales personnel will also gain a better knowledge of the customer's needs as well as learn to determine exactly what questions they should be asking the customer and what the customer's responses mean. In this manner, the book will offer invaluable tips to ensure customers get exactly what they expect in a system.
* Provides a detailed explanation of CCTV components and the technology behind analog and digital CCTV systems.
* Establishes a "common language" for security professionals, CCTV system designers and sales personnel to use as a basis for system design.
* Provides a clear explanation of the design process and design principles.
